Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40828, here are decompositions:
- 5 + 40823 = 40828
- 41 + 40787 = 40828
- 89 + 40739 = 40828
- 131 + 40697 = 40828
- 191 + 40637 = 40828
- 251 + 40577 = 40828
- 269 + 40559 = 40828
- 401 + 40427 = 40828
Showing the first eight; more decompositions exist.
